- •
Abnormal inferior Q waves may be the remnants of a previously unsuspected myocardial infarction.
- •
We evaluated the diagnostic accuracy of electrocardiogram during inspiration and echocardiography.
- •
Magnetic resonance is the gold standard method to detect myocardial infarction.
- •
Inferior Q waves persistence is a strong marker of silent myocardial infarction.
- •
Echocardiography segmental wall motion analysis has lower sensitivity and specificity.
